Learn how to determine the number of moles in a given set of atoms using Avogadro's number. This tutorial breaks down the calculation for Aluminum and Iron, simplifying the concept for better understanding.

Understanding pH Values: In this video we break down the pH levels of various solutions. Discover the importance of acid strengths via Ka and pKa contrast weak vs. strong acids and learn the counterintuitive relationship between pOH and pH.

This video outlines the process of calculating the number of moles in various elemental samples. It begins by explaining the relationship between molar mass and atomic weight. Each sample's mass is divided by the respective element's molar mass to find the number of moles. It provides detailed calculations for four elemental samples: zinc (Zn), argon (Ar), tantalum (Ta), and lithium (Li), converting results to scientific notation where necessary. The script demonstrates how to determine the mole
